A set of 10 FC/A attenuation elements (male and female) with varied attenuation values: 0 dB, 3 dB, 5 dB, 7 dB, 10 dB, 12 dB, 15 dB, and 20 dB. Designed to reduce signal power in fiber optic systems, helping protect receivers and other components while enabling accurate link budgeting and testing. Compatible with FC/A connectors for easy installation and seamless integration into existing FC/A networks. Fixed FM attenuator with flange for secure, stable connection and reliable performance in field or lab environments. Benefits at a glance - Precise, selectable attenuation across a wide range - Robust mechanical design built for routine use in installations and tests - Simple replacement and compatible with common FC/A interfaces Applications - Calibrating receiver sensitivity and verifying performance in FC/A fiber links - Testing and simulation setups to emulate longer or lower power links - On site protection of receivers during maintenance, commissioning, or troubleshooting
